Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the north and northwest side of the Houston area and "Moderate" in the Dallas-Fort Worth, El Paso, and Tyler-Longview areas, with highest concentrations in the afternoon and early evening.

Slightly elevated background levels associated with a mixed air mass containing light amounts of continental haze combined with sufficient local add-on could be enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in parts of the Beaumont-Port Arthur, Dallas-Fort Worth, Houston, and Tyler-Longview areas.
